This is a list of all the upgrades in the game, and their effects. Not a strategy guide.
Since (to my knowledge) there is no comprehensive list of all the upgrades an their various effects anywhere online or in the game, I have decided to create my own using data gathered from upgrade stations in runs and my own testing. It’s basically a compilation of notes I took while playing in order to help me remember what upgrades did what when the slugs appeared in the Hub, so please correct me if I got anything wrong.
Autobarrier
Enemies that drop pearls create barriers on death.
(The barrier is a small circle that appears where an enemy is defeated, and absorbs a few bullets.)
Axolotl
+1 HP per stage for 4 stages
+5% POW per stage afterwards
(The POW from this upgrade ignores your max POW limit)
Battery
Special bombs give stat boost on use
PLASMA: +5% Damage
MEND: +2 HP
BARRIER: +Shield
(These effects are all the same effect as picking up a special bomb when full on bombs, except for Mend Bombs which have this effect doubled.)
Blink
Dash teleports
(The dash no longer has any effect on your momentum, and instead instantly moves you in a direction. It also feels like this dash has a slightly longer cooldown?)
Bounty Hunter
More caches and cache nodes
Cloak
No contact damage
Triple invincibility frames after being hit
Crown
Bosses drop double pearls (At least 400, instead of at least 200)
+30% Max POW (Max POW becomes 60%)
Deadeye
Improves all weapons
BASIC: nothing
FLARE: + range
BURST: + range & accuracy

Reroll into anything
(Effects only trigger when rerolling a shop’s items with a bomb)
Hourglass
Extends the Pearl Chain timer significantly.
(Feels like at least double the duration)
Ionize
Weapons shoot bonus bullets
Scales with POW (no effect at 0%, small effect at 5%, maximum effect at 30%)

BURST: extra bullets appear perpendicularly after the base bullets expire or hit something
PUNCHER: extra bullets appear & “bounce back” towards you after the base bullets expire or hit something
NEEDLER: extra bullets appear while charging, and target the nearest enemy
FIREBALL: extra bullets appear in a spray after the base bullet hits something
LASER: extra bullets appear perpendicularly all along the fully charged beam
AURA: extra bullets appear in a spray around the base bullet as it moves. (fewer bullets spray for the half-charge version)
FLAKSHOT: extra bullets appear after applying the damage over time effect, and target the nearest enemy to the enemy taking damage over time.
Magazine
Get random weapon next 3 stages
+10% damage
+10% POW
(This upgrade does not take into account your current weapon when choosing a new random one. So for example you could go from PUNCHER to buying FLARE to being randomly given FLARE)
Shell
Bomb on next 4 hits (seems to activate after taking damage)
Double bomb duration
Sushi
+4 HP
Shops sell food items
CRAB CLAW +1 HP +1 Shield
